Session: BRK2485
What is SDS?
- Cloud-inspired infrastructure and design – Commodity HW, cost efficiencies
- Evolving technologies – Flash, network performance, VMs and containers
- Data explosion – Device proliferation, modern apps
- Scale out with simplicity – Integrated solutions, rapid time to solution, policy-based management
Storage Customer choice: Private cloud with traditional storage (SAN/NAS), private cloud with Microsoft SDS (Azure stack storage), hybrid cloud storage (StorSimple with Azure storage), public cloud storage (Azure storage) Where are we today in the SDS journey? -Goes into details about WS2012 R2 solutions, including those from Dell. What’s in Technical Preview 2 of WS2016?
- Reliability – Cross-site availability and DR, improved tolerance to transient failures
- Scalability – Manage noisy neighbors and demand surges, deploy mixed workloads in shared environment
- Manageability – Easier migration to the new OS version
- Reduced cost – More cost-effective by using volume HW, use SATA and NVMe in addition to SAS
Storage QoS
- Simple out of box behavior – Enabled by default on scale out file server, automatic metrics per VHD, VM, host, volume; includes normalized IOPs and latency
- Flexible and customizable policies – Policy per VM, VHD, service or tenant; fair distribution within policy
- Management – System Center VMM and Ops Manager; PowerShell built-in for Hyper-V and SoFS
Rolling Upgrades
- Simple – Rolling upgrade within cluster
- Seamless – Zero downtime for Hyper-V and scale-out file server
VM Storage resiliency: reliability
- Resiliency – Freezes VMs if storage path is lost
- Visibility –
Storage Replica
- Protection of key data and workloads
- Synchronous replication – Storage agnostic mirroring with crash-consistent volumes
- Increase resilience – Metro distance clustering
- Complete solution – End-to-end for storage and clustering
- Streamlined management – GUI management for nodes and clusters
Storage Spaces Direct
- Cloud Design points and management – Standard servers with LOCAL storage, supports NVMe
- Reliability, scalability, flexibility – Fault tolerance to disk, enclosure and node failures
- Use cases – Hyper-V IaaS storage, hyperconverged
- Partners: HP Apollo 2000, Quanta D51PH, Lenovo x3650, Dell, Cisco
- Uses ReFS as the underlying filesystem
Azure-consistent storage (future preview)
- Consistent – Azure consistent blob, table, and account management for on prem
- Integrated – Deployed as Microsoft Azure stack cloud services
- Manageable – Azure cmdlets, APIs and templates
- Scalable – PaaS services as front-end, high-performance scale-out IaaS via internal SMB
Demo shows 100Gb NIC and NVMe Direct Storage with <1ms latency and 11GB (bytes) throughput over 1 network port. WOW! They literally saturated a 100Gb NIC with SMB traffic. Approximately 20% CPU utilization.
